This is irrelevant to your question,but how does one take a screen shot.On computers I,ve had before there was a button to do this,but not on the computer I have now. I used to find it very useful.
It's usually on the top row of the keyboard.. Mine has "Prt scr" on it. Press that while on the screen you want to take a shot of, open up Paint and paste the image.
I found it stopped dead a couple of times this morning (on Firefox), but then it picked up again. I imagine the Ed had taken his finger off the power supply button while he ate a biscuit.
